Description
This option assumes video is being blended upstream into one VLAN. A WAN port is configured as
Untagged (the default), and both data and video are routed through to LAN clients. This is a common
scenario. This is the default.
For this option, data traffic comes in Untagged (the default). For video traffic, a WAN port is configured
with a video-only Tagged VLAN. In this case, you must manually define which ports are members of
the "video service", e.g., explicitly bind the WiFi 5 GHZ and two LAN ports to the video service. The
video service is then bridged through to the video-only VLAN on the WAN.
The drawback to this arrangement is if a customer plugs a device into the wrong port, they cannot
connect to the expected services. In this mode, IGMP proxy is not used (just snooping). The video
VLAN bridges to the devices in the home on the video VLAN. This means that (without proper ACLs in
the upstream DSLAM), the user can also see the neighbors' DVRs and STBs. The reason you need to
identify an SSID here is because you have a video SSID and data SSID and you want to bridge to the
correct SSID (the video SSID).
This option assumes that Internet and video are coming in on separate VLANs. A typical use case would
be data coming in as Untagged and video coming in as Tagged VLAN 3.
You then use IGMP proxy from LAN hosts to the video VLAN and route all unicast (data) to the data
service (Untagged). The net result is same as above, meaning any wireless interface or LAN port can
receive internet data and video; it doesn't matter to which port the user connects an STB.
